Abstract

L'invention concerne un dispositif électronique (1) comprenant un boîtier arrière (10), un objectif (20), un appareil photo (30), et un module de reconnaissance d'empreinte digitale (40). Une portion de trou traversant pénétré (100) est formée sur le boîtier arrière (10). L'objectif (20) est monté au niveau de la portion de trou traversant (100) et comprend une portion de lentille d'appareil photo (210) et une portion de lentille de reconnaissance d'empreinte digitale (220) reliées l'une à l'autre. L'appareil photo (30) est placé sur le côté avant de l'objectif (20) et fait directement face à l'avant et à l'arrière de la portion de lentille d'appareil photo (210). Le module de reconnaissance d'empreinte digitale (40) comprend un capteur d'empreinte digitale (400) et une carte de circuit imprimé souple (410) connectée électriquement à celui-ci. Le capteur d'empreinte digitale (400) est placé sur la surface avant de la portion de lentille de reconnaissance d'empreinte digitale (220) et fait directement face à l'avant et à l'arrière de celle-ci.
